Software Engineer Interview Experience - United Kingdom
Process
All coding rounds went well. When it came to the system design round, I was unlucky and got a bad interviewer. I've interviewed with more than 20 firms now, so I know a bad interviewer when I see one. He explained the problem well, but instead of trying to understand my way of thinking, he had a set solution in mind and rigidly tried to steer me there, becoming upset when I attempted to discuss another approach. Overall, it was a weird interview.
I was rejected for "bad communication skills in system design round." I received several offers from better firms, so I guess I was unlucky to get a bad interviewer. Everyone else was good and nice.
Questions
Some system design and coding rounds. Coding challenges are LeetCode medium, maybe easier.

Palantir Work Experiences
- 4.0Big tech, top-tier pay in LondonSoftware Engineer • Former EmployeeLondon, England, United KingdomJuly 17, 2025Pros: Good pay and benefits. Large established team with smart peers. Very mature tech stack.Cons: Large amounts of internal systems can sometimes be hard to navigate. Product direction is driven by large customers.
- 5.0Amazing people, great tech, long hoursSoftware Engineer • Former EmployeeJune 12, 2021Pros: People are amazing; the hiring quality is out of this world even for the Valley. Projects can be extremely interesting. Tech stack (especially on the Foundry side) is modern and fun to use. The software is real and works unlike most enterprise technology Palantir competes against.Cons: Work/life balance is highly project dependent. Long hours trend towards brutal if your project is fast-paced or the customer is overly demanding. Your project may not be all that interesting, and you'll hear about everyone else doing world-changing tech. If your project is uninteresting and has long hours, you can burn out fast. Some of the Gotham codebase is archaic and hard to understand. Palantir changes over time, and you'll need to adapt or reinvent yourself if you stay longer than two years. This can be fun but stressful, and the pace never slows down.
- 5.0Amazing culture working on the world's hardest problemsSoftware Engineer • Former EmployeeApril 28, 2022Pros: Pushed to the edge, promote from within, world's most interesting problems, the people.Cons: can be demanding, can take some time adjusting.
